In this tutorial you will learn how to create a simple HTML Login form like the one below. The design was taken from ColorLib, I simply recreated it from scratch.

html login form

We will only use HTML and CSS, no Bootstrap, no JavaScript.

Setup

Before we start writing the markup for our form, let's import a couple of things: - fontawesome - Roboto, our google font Go ahead and paste this code inside the head tag of your index.html file.

<a
  rel="stylesheet"
  href="https://use.fontawesome.com/releases/v5.3.1/css/all.css"
  integrity="sha384-mzrmE5qonljUremFsqc01SB46JvROS7bZs3IO2EmfFsd15uHvIt+Y8vEf7N7fWAU"
  crossorigin="anonymous"
/>
<a href="https://fonts.googleapis.com/css?family=Roboto:300,400" rel="stylesheet" />

Now we can move on to writing our markup. We will first write all the HTML and then start styling it with CSS. The structure is fairly simple: - form_wrapper is our main contaner that we will position in the middle of the page - form_left will be the container for the image - form_right will be the container for our input tags - input_container holds a i containing a font-awesome icon and an input tag

<body>
  <div id="form_wrapper">
    <div id="form_left">
      <img src="icon.png" alt="computer icon" />
    </div>
    <div id="form_right">
      <h1>Member Login</h1>
      <div class="input_container">
        <i class="fas fa-envelope"></i>
        <input placeholder="Email" type="email" name="Email" id="field_email" class="input_field" />
      </div>
      <div class="input_container">
        <i class="fas fa-lock"></i>
        <input
          placeholder="Password"
          type="password"
          name="Password"
          id="field_password"
          class="input_field"
        />
      </div>
      <input type="submit" value="Login" id="input_submit" class="input_field" />
      <span>Forgot <a href="#"> Username / Password ?</a></span>
      <span id="create_account">
        <a href="#">Create your account ➡ </a>
      </span>
    </div>
  </div>
</body>

< path="/javascript-carousel" />

Now it's the fun part: styling with CSS. To achieve the expected result we will use flexbox and grid layouts alongside with CSS variables to store our colors. Storing values inside CSS variables will make changing colors very easy, have a look at this code:

:root {
  --body_gradient_left: #7200d0;
  --body_gradient_right: #c800c1;
  --form_bg: #ffffff;
  --input_bg: #e5e5e5;
  --input_hover: #eaeaea;
  --submit_bg: #1fcc44;
  --submit_hover: #40e263;
  --icon_color: #6b6b6b;
}

Good, now we will apply some default styling to override the browser default:

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

The next step is to start styling the body and the form_wrapper Read the comments to better understand what we are doing here.

body {
  /* make the body full height*/
  height: 100vh;
  /* set our custom font */
  font-family: 'Roboto', sans-serif;
  /* create a linear gradient*/
  background-images: [ linear-gradient(
    to right,
    var(--body_gradient_left),
    var(--body_gradient_right)
  );
  display: flex;
}

#form_wrapper {
  width: 1000px;
  height: 700px;
  /* this will help us center it*/
  margin: auto;
  background-color: var(--form_bg);
  border-radius: 50px;
  /* make it a grid container*/
  display: grid;
  /* with two columns of same width*/
  grid-template-columns: 1fr 1fr;
  /* with a small gap in between them*/
  grid-gap: 5vw;
  /* add some padding around */
  padding: 5vh 15px;
}

On the left side we simply want to display an image centered.

#form_left {
  /* center the image */
  display: flex;
  justify-content: center;
  align-items: center;
}

#form_left img {
  width: 350px;
  height: 350px;
}

Now let's move to styling the form_right container

#form_right {
  display: grid;
  /* single column layout */
  grid-template-columns: 1fr;
  /* have some gap in between elements*/
  grid-gap: 20px;
  padding: 10% 5%;
}

And this is the style for the input tags:

.input_container {
  background-color: var(--input_bg);
  /* vertically align icon and text inside the div*/
  display: flex;
  align-items: center;
  padding-left: 20px;
}

.input_container:hover {
  background-color: var(--input_hover);
}

.input_container,
#input_submit {
  height: 60px;
  /* make the borders more round */
  border-radius: 30px;
  width: 100%;
}

.input_field {
  /* customize the input tag with lighter font and some padding*/
  color: var(--icon_color);
  background-color: inherit;
  width: 90%;
  border: none;
  font-size: 1.3rem;
  font-weight: 400;
  padding-left: 30px;
}

.input_field:hover,
.input_field:focus {
  /* remove the outline */
  outline: none;
}

#input_submit {
  /* submit button has a different color and different padding */
  background-color: var(--submit_bg);
  padding-left: 0;
  font-weight: bold;
  color: white;
  text-transform: uppercase;
}

#input_submit:hover {
  background-color: var(--submit_hover);
  /* simple color transition on hover */
  transition: background-color, 1s;
  cursor: pointer;
}

Now let's finish by styling our h1 and our span and a tags

h1,
span {
  text-align: center;
}

/* shift it a bit lower */
#create_account {
  display: block;
  position: relative;
  top: 30px;
}

a {
  /* remove default underline */
  text-decoration: none;
  color: var(--submit_bg);
  font-weight: bold;
}

a:hover {
  color: var(--submit_hover);
}

i {
  color: var(--icon_color);
}

Perfect. You now have a good-looking, simple HTML form. Let's add a few more line of CSS to make sure that it will look nice even on smaller screens:

/* make it responsive */
@media screen and (max-width: 768px) {
  /* make the layout  a single column and add some margin to the wrapper */
  #form_wrapper {
    grid-template-columns: 1fr;
    margin-left: 10px;
    margin-right: 10px;
  }
  /* on small screen we don't display the image */
  #form_left {
    display: none;
  }
}
